When I started covering energy efficiency and retrofits for landlords, one thing became obvious fast: retrofit clauses in tenancy agreements are a powerful tool—if drafted smartly. They can secure access, protect investments, and speed up energy upgrades that benefit landlords, tenants and the planet. They can also create legal headaches if they're vague or overreach. In this piece I share what...

As someone who has spent years covering energy systems and community-scale solutions, I’ve seen firsthand how a well-drafted heat-as-a-service (HaaS) contract can transform local heating provision — and how a poor one can lock a council into decades of high bills and missed targets. If your...

I’ve been thinking a lot lately about one of the most overlooked opportunities in the energy transition: supermarket cold stores. These facilities already consume large amounts of electricity, require reliable power for refrigeration, and often have sizable roof and yard spaces. What if they...

When I first started exploring renewable solutions for events, the idea of a pop-up solar charging hub powering an entire festival sounded ambitious—maybe even impossible. Over the years I've seen small, well-designed systems not only charge phones and laptops, but also support lighting, sound...

I’ve had conversations with dozens of homeowners, installers and energy traders about this exact question: can a Tesla Powerwall owner in the UK legally export stored power back to the grid and actually earn money from it? The short answer is yes — but with important caveats. In this piece...

Retrofitting a 1930s semi for heat pumps and airtightness is one of those projects that feels equal parts exciting and nerve-wracking. I’ve worked through a few of these homes, and what I’ve learned is that you can dramatically improve comfort and efficiency without turning the house into a...

I’ve watched second‑life EV batteries move from a niche concept to a practical option for community microgrids, and I’m still struck by how many questions remain about real savings—and who actually pays when things go wrong. In this piece I want to walk you through the economics, the...

I’ve worked with landlords, tenants and energy professionals long enough to know that pushing for energy-efficient retrofits isn’t just good for the planet — it makes financial and reputational sense. Whether you own a single buy-to-let or manage a small portfolio, knowing which clauses to...

I often get asked whether an achat de véhicule utilitaire par une SCI is a sensible move. The question sits at the intersection of company law, tax strategy, and practical fleet management — and it's particularly relevant for property-owning structures like a Société Civile Immobilière (SCI)...
